Christians often say that they hate the sin not the sinner. I say that I hate the belief not the believer.
I'll do you one better: hate the underlying fundamental flaws in human nature, not the inevitably flawed human institutions which arise from them.
(I'm not trying to jerkily blow up your argument. I have this intellectual tic where I look for the conceptual "lowest common denominator" in everything--like trying to construct a kind of philosophical unified field theory.)
I think some people need christianity, so I just really try to stay out of it. I don't have any hate for it. There was a time in my life when I thought I wanted to be a christian but I never really got it, so it hasn't done anything to me. I only say that some people need it cause it might be the only way they can be halfway good.
I say something that means the same thing but gets to the thing I actually hate which is faith. I say "I hate faith not the faithful" Faith has been made to be a vertuois thing when it's actually the suspension of reason. It literally suspends the person's ability to question his/her beliefs.
